Radiance runs more slowly compiled by icc. The rpict time of gcc 4.5.2 is around 17 minutes 45 seconds and the rpict time of icc V12 Update 6 is 20 minutes. The binaries (elf files) produced by the Intel compiler are 1 MB which is twice the size of the binaries produced by gcc. Another idea is to post a message on an Intel forum, informing them about gcc's better performance, they seem interested in this kind of information. Maybe Intel can learn from gcc and improve their own compiler. Guy
